* Alignment and Vibration Isolation: Izumi, Okutomi * BF yaw transfer function showed that it did not move well. It was fount that the position of IP was different from when pumping down started. * IP drifted 2mm in the air, and another 2mm when pump down. (Takahashi) * ETMY IPs were set back to where they were on 1/13. The transfer function now has the similar shape as before, but the Q of lowest peak is a bit low. |
* Alignment and Vibration Isolation: Izumi, Miyakawa * Drift by cooling is smaller than that of pump down. * Cooling: Kimura, Suzuki, Yokozawa * 4k cooler, 50k cooler started. * PLC values are not available. |
Line 65: | Line 68: |
* Alignment: Miyakawa * We keep the eye on the oplev response and correct the alignment if drift is much. |

* Alignment and Vibration Isolation: *Izumi * We can move moving masses of BF, or IPs of yaw to check TF can be recovered. * We will play one more day under vacuum. * Type A: *Yokozawa * RT model of Type A will be separated into cryopayload and tower. * Type B * SR assembly continues. * Laser hazard: PSL. Green might be used late of the afternoon, then the center area and Y end will be the hazard area. |
* Laser hazard: All area related to inside the vacuum. |

* Finding causes of ETMY trouble. * Vent might be needed if ETMY is touching somewhere. * Cooling also will be delayed for 2weeks or so. |
* 2/7 Cooling. |
